Ingabe Umehluko Wezinguqulo Ze-Bluetooth Ubalulekile? Umlando we-Bluetooth v1.0 kuya ku-v5.0

Ingabe uyazibuza Bluetooth Izinguqulo Umehluko? I-Bluetooth yigama lobuchwepheshe befrikhwensi yomsakazo webanga elifushane elisusa isidingo sokuxhuma ngezintambo. I-Bluetooth yasungulwa ngo-1994 yinkampani yakwa-Ericsson ukuxhumana ngokungenantambo nomakhalekhukhwini namanye amadivaysi eselula. Iqanjwe ngegama likaHarald Bluetooth (owayeyinkosi yaseDenmark).

Uyini Umehluko wenguqulo ye-Bluetooth

Umehluko oyinhloko wezinguqulo ze-Bluetooth ukuthi izinguqulo zakamuva ze-Bluetooth zisekela isivinini sokudlulisa idatha, zinebanga lokuxhumana elingcono nokuzinza, zonga amandla kakhudlwana, futhi zinikeza ukuvikeleka okungcono kunezinguqulo ze-Bluetooth ezindala. Yebo umehluko wezinguqulo ze-bluetooth awukona nje lokho.

I-Bluetooth 1.0

Ngenkathi i-Bluetooth v1.0 isungulwa ngo-1998, kwaba ukutholakala okudabukisayo. Kodwa-ke, ubuchwepheshe bebungakavuthwa futhi buhlushwa izinkinga eziningi ezifana nokungaziwa. Ngokwezindinganiso zanamuhla, ubuchwepheshe manje abusebenzi.
I-Bluetooth v1.1 yalungisa ezinye zezinkinga, kodwa izinkinga ezinkulu zasingathwa ngokwethulwa kwe-Bluetooth v1.2. Umehluko wezinguqulo ze-Bluetooth wukuthuthukiswa okubalulekile okuhlanganisa ukusekelwa kwe-adaptive frequency hopping (AFH) spectrum, enciphisa ukuphazamiseka, isivinini sokudlulisa esisheshayo esifika ku-721kbps, ukuxhumeka okusheshayo nokutholwa, I-Host Controller Interface (HCI) kanye Noxhumano Olunwetshiwe Lwe-synchronous (ESCO).

I-Bluetooth 2.0

I-Bluetooth v2.0 yakhululwa ngaphambi kuka-2005. Okugqamile kwaleli zinga kwaba ukusekelwa kwe-Enhanced Data Rate (EDR), esebenzisa inhlanganisela ye-Phase Shift Keying Modulation (PSK) ne-GFSK ukuze vumela izivinini zokudlulisa idatha ezingcono.
Ubuchwepheshe bathuthukiswa futhi ngokukhululwa kwe-Bluetooth v2.1. Manje isisekela ukubhanqa okulula okuvikelekile (i-SSP), okuthuthukise ukuvikeleka nolwazi lokumatanisa, kanye nokuphendula kwemibuzo okuthuthukisiwe (EIR), okuvumele ukuhlungwa okungcono kwamadivayisi ngaphambi kokusungula uxhumano.
Kuzo zonke izinguqulo zakudala ze-Bluetooth, i-v2.1 ibithandwa kakhulu futhi isetshenziswa kabanzi. Lokhu kwakungenxa yobulula bayo, ibanga elide lika-33 m esikhundleni sika-10 m, kanye nesivinini sokudlulisa idatha esisheshayo esingafika ku-3 Mbit/s esikhundleni sika-0.7 Mbit/s.

I-Bluetooth 3.0

I-Bluetooth v3.0 yakhululwa ngo-2009 futhi yethulwa imodi yesivinini esikhulu (HS), evumele idatha yetiyori isivinini sokudlulisa esingafika ku-24 Mbps ngesixhumanisi esihlanganisiwe esingu-802.11. Lobu buchwepheshe bethule izici eziningi ezintsha, ezifana Nokulawula Amandla Okuthuthukisiwe, I-Ultra Wideband, Izindlela Ezithuthukisiwe ze-L2CAP, I-Alternate MAC/PHY, I-Unicast Connectionless Data, njll. Kodwa-ke, bube ne-drawback eyodwa enkulu - ukusetshenziswa kwamandla aphezulu.Ngenxa yale nkinga, amadivayisi ukusebenzisa i-Bluetooth 3.0 kudle amandla amaningi kakhulu kunabandulelayo, okuholele ekutheni impilo yebhethri emfushane yamadivayisi anikwe amandla i-Bluetooth. Njengomphumela, i-Bluetooth v2.1 yahlala idumile ngamadivayisi amasha asekela i-Bluetooth v3.0.

I-Bluetooth 4.0

I-Bluetooth v4.0 yakhululwa ngo-2010 futhi iyavela bluetooth izinguqulo umehluko is yethule usekelo lwe-Bluetooth Low Energy. Ngaleso sikhathi, yayimakethwa njenge-Wibree ne-Bluetooth Smart. I-Bluetooth 4.0 isekele zonke izici zezinguqulo zangaphambilini, kodwa ushintsho olubaluleke kakhulu kwakuwukusetshenziswa kwamandla. Okungukuthi, amadivaysi e-BLE anganikwa amandla ibhethri yeseli yemali. Ngakho-ke kwase kuyenzeka manje ukuthuthukisa amadivaysi ahlangene futhi aphathekayo angasebenza izinsuku kubuchwepheshe be-Bluetooth.
I-Bluetooth v4.1 yethulwa ngo-2013 ukuze kuthuthukiswe ulwazi lomsebenzisi. Manje isingasetshenziswa kanye ne-LTE, inike amandla amadivayisi ukusekela imisebenzi eminingi ngesikhathi esisodwa, futhi yenza kube lula ukudluliswa kwedatha enkulu.
Imisebenzi emisha esekelwa yilesi sici ihlanganisa:

  • I-Low Duty Cycle Eqondiswa Ukukhangisa 802.11n PAL
  • Isikhathi sokuthola esilinganiselwe
  • I-LE Link Layer Topology
  • Iziteshi ezigxile ku-L2CAP ezixhumene nezizinikele ezinokulawulwa kokugeleza okusekelwe kusikweletu
  • Ukugudluza Isitimela kanye Nokuskena Okuhlanganyelwe Okujwayelekile
  • Isikhawu esisheshayo sokukhangisa kwedatha
  • Ukubonisana ngokuhlanganyela kwamasevisi angenantambo eselula
  • Imodi ekabili kanye ne-topology
  • Isakhiwo somsindo esibuyekeziwe sokudluliswa kwezwi elibanzi

I-Bluetooth v4.2 yakhululwa ngo-2014 futhi yenza i-Intanethi Yezinto (IoT) yenzeka. Ukuthuthukiswa okubalulekile kufaka phakathi:

  • Vikela ukuxhumeka kwamandla aphansi ngokunwetshwa kobude bephakethe ledatha.
  • Iphrofayili Yokusekelwa Kwephrothokholi Ye-inthanethi (IPSP) inguqulo 6 ilungele Izinto Ezihlakaniphile ze-Bluetooth ukusekela ikhaya elixhunyiwe
  • Xhuma Ubumfihlo Besendlalelo Ngezinqubomgomo Zokuhlunga Zeskena ezithuthukisiwe

I-Bluetooth 5.0

I-Bluetooth v5.0 yethulwa ngo-2016 yi-Bluetooth SIG, kodwa ukusekelwa kwe lobu buchwepheshe baqala ukusetshenziswa ngabakwaSony emkhiqizweni wabo we-Xperia XZ Premium. Umehluko omkhulu wezinguqulo ze-bluetooth usezingeni igxile ekuthuthukiseni ukuxhumana kanye nolwazi lwe-inthanethi Yezinto (IoT). ngokunikeza ukuhamba kwedatha okungenazihibe.
Ku-BLE, isivinini esiphindwe kabili ekuqhumeni okungafika ku-2 Mbps manje kusekelwa phakathi kwebanga elilinganiselwe elingafika ngokuphindwe kane ububanzi besizukulwane sangaphambilini, okusho ukuhwebelana ngesivinini sokudlulisa idatha.
Izindawo zokuthuthukisa yilezi:

  • Imaski yokutholakala kwesikhala (SAM)
  • Izandiso Zokukhangisa ze-LE 2 Mbps PHY ye-LE
  • I-LE Long Range
  • I-High Duty Cycle Ukukhangisa Okungaxhumeki
  • I-Algorithm Yokukhetha Isiteshi

Futhi, kukhona umehluko we-bluetooth opholile obizwa ngokuthi I-'Dual Audio' yethulwe evumela amadivaysi amabili e-Bluetooth ahlukene njenge ama-headphones angenantambo noma izipikha ukudlala ngesikhathi esisodwa umsindo ovela kudivayisi eyodwa yokusakaza yomsindo ye-Bluetooth esekela le nguqulo. Kungenzeka futhi ukusakaza imithombo yomsindo emibili ehlukene kusuka kudivayisi yokusakaza efanayo iye kumadivayisi amabili e-Bluetooth ahlukene.
I-Bluetooth v5.3 inguqulo yakamuva, ekhishwe ngo-2022, okuyinto yethule ukusekelwa kwemodeli esekwe kwi-mesh ukubusa. Nakuba le nguqulo ingakasetshenziswa kabanzi, akungabazeki ukuthi ikusasa lobuchwepheshe be-Bluetooth, obuzoqhubeka nokuba ngcono.

Ukuthuthukiswa okuyinhloko yilezi:

  • I-Angle of Arrival (AoA) kanye ne-Angle of Departure (AoD) isetshenziselwa indawo yedivayisi nokulandelela.
  • Ukuhanjiswa kokuvumelanisa okuvamile kwezikhangiso
  • Ukulondoloza isikhashana kwe-GATT
  • Inkomba yesiteshi sokukhangisa

Izithuthukisi ezincane zihlanganisa:

  • Icacisa ukuziphatha kokwephulwa kwemithetho
  • Ukusebenzisana phakathi kweQoS nokucaciswa kokugeleza
  • Inkambu ye-ADI kudatha yempendulo yokuskena
  • Ukuhlelwa kwesiteshi sosokhaya sezikhangiso zesibili
  • Ukusekelwa kwe-HCI kokhiye bokususa iphutha ku-LE Secure Connections
  • Buyekeza indlela yokunemba kwewashi lokuphumula
  • Vumela ukuboniswa kwe-SID emibikweni yempendulo yokuskena
